According to TMZ’s post, Demi Moore was into Red Bull addiction for years and now under recovery for the said addiction,

Moore — a recovering addict — had cases and cases of Red Bull delivered to her home as early as 2002. Sources connected with Red Bull North America tell us … Demi was so dependent on the energy drink, the company used her to market the product.

With Demi’s Red Bull addiction, she would rather drink tons of Red Bull than alcohol in parties she had attended, also said in TMZ’s post.
